Fastrack question

How many hours before I should change the hydrogear oil in my Fastrack 52/20?

What type of oil/fluid is recommended? Viscosity? Amount required to fill?

It does not look like there is a drain plug on the bottom of each hydrogear housing..Am I missing something, or do I have to drop the whole bottom of the housing, and replace the gasket when I want to change this fluid?

The Hydro Gear units used in the FasTrak are not serviceable.
There is not a drain plug to change the fluid, Hydro Gear does not recommend that the units be "opened" up at all.
Hydro Gear does not recommend changing the hydro fluid.
